\section{Obtaining output}
\index{output}

The two commands mostly used to obtain information from a \MMonCa\ simulation are:
\begin{description}
\item[extract\index{extract}]  It extracts profiles, concentrations, defect numbers, etc... in plain ASCII text. See~\ref{sec:extract}.
\item[save\index{save}] It saves the atomistic information in {\tt xyz} or {\tt ovito} format for visualization. See~\ref{sec:save}.
\end{description}

Extract can collapse the information in 1, 2 and 3 dimensions with the use of the {\tt dimension}\index{dimension} option.
